BPEL Designer extensionActivity bughttps://www.eclipse.org/forums/index.php/mv/msg/177830/565203/#msg_565203
I fixed the problem with the BPEL designer crashing when it tries to load an extensionActivity that does not have a supporting extension plug-in. It now shows up as a simple activity with not Property Sheet info - you have to use the editor's source tab to edit the enclosed extension activity's attributes.

Of course, the right way to do this is to write an extension point for the editor to support the invokeService and invokePipelet activities. There's a pretty good example of how to do this in the CVS repo in examples/plugins.
